What is 4???

c.-1 and 4 because thats where it intercepts

f(3) = -5*3^2 - 3 + 20 = -5*9 - 3 + 20 = -45 - 3 + 20 = -28;

Answer: - 28

Step-by-step explanation:

f(x) = -5x^2 - x + 20

To find f(3), we simply put x = 3 and then simplify

f(3) = - 5(3)^2 - 3 + 20

= -5(9) - 3 + 20

= -45 - 3 + 20

= -48 +20

= -28

f(3) = -28

Answer:- The set must have a constant additive rate of change.

Explanation:-

Let X be a data set contains an independent and dependent variable.

The standard linear function is given by

[tex]y=mx+c[/tex]  , where x is a independent variable and y is a dependent variable and m,c are the constants.

for m =1, y=x+c

for m=2, y=2x+c=x+x+c

for m=3, y=3x+c=x+x+x+c

1.Thus ,the set must have a constant additive rate of change.

2.The set must not have a constant multiplicative rate of change as the function will become exponential function given by [tex]y=Ab^X[/tex] which is not linear .

3.The values in the set can be positive or negative as the domain for linear function is the set of real numbers.

4.The values in the set must be increasing it is not necessary.

Final answer:

To find the values of x and y, set up an equation by equating the two angles and solve for x and y using the given measures.

Explanation:

To find the values of x and y, we need to equate the two angles and solve for x and y.

According to the given information, the measure of one angle is 2x, while the measure of the other angle is 2y - 10.

Since the two angles are equal, we can set up the equation: 2x = 2y - 10.

Now, we can solve for x and y.

2x = 2y - 10
x = y - 5

So, the value of x is y - 5.

The values for x and y are found by solving the system of equations that arise from setting up the condition that two angles forming a linear pair add up to 180 degrees and are equal. The solution is x = 45 and y = 50.

The student's question involves finding the values of x and y when two lines intersect to form a linear pair with equal measures. Since the angles form a linear pair, they add up to 180 degrees. Therefore, we must set up an equation 2x + (2y - 10) = 180 to find the values of x and y. Because the question tells us the angles are equal, we also know that 2x = 2y - 10. Solving this system of equations will provide the values for x and y.

To solve for x, we can use the second equation directly, 2x = 2y - 10. Since the angles are equal, we substitute the first angle's measure for the second, meaning x = y - 5. Then, we can substitute x into the first equation: 2(y - 5) + 2y - 10 = 180, simplifying it to 2y - 10 + 2y - 10 = 180, which further simplifies to 4y - 20 = 180. Finally, adding 20 to both sides and then dividing by 4 gives us y = 50. With the value of y, we can then find x: x = y - 5, so x = 50 - 5, meaning x = 45.

Answer:

For k12- the answer is Quadrilateral RSTU is not a rectangle because it has no right angles.

Step-by-step explanation:

Solution: A quadrilateral RSTU whose vertices are  R(−4, 1) , S(4, −1) , T(3, −6) , and U(−5, −4).

RS = [tex]\sqrt{(4+4)^{2}+(-1-1)^{2}} =\sqrt{64+4}= \sqrt{68}[/tex]

ST= [tex]\sqrt{(4-3)^{2}+(-1+6)^{2}}= \sqrt{1+25} =\sqrt{26}[/tex]

TU=[tex]\sqrt{(3+5)^{2}+(-6+4)^{2}}= \sqrt{64+4}= \sqrt{68}[/tex]

UR =[tex]\sqrt{(-5+4)^{2}+(-4-1)^{2}}= \sqrt{1+25} =\sqrt{26}[/tex]

→RS=TU, and ST=UR⇒ Opposite sides are equal.

Slope of RS = [tex]\frac{-1-1}{4+4} = \frac{-2}{8}=  \frac{-1}{4}[/tex]

Slope of TS= [tex]\frac{-6+1}{3-4} =\frac{-5}{-1}=5[/tex]

Slope of RS × Slope of TS = -1/4 × 5 = -5/4 ≠ -1, So lines are not perpendicular.

∴ quadrilateral RSTU  is not a rectangle.

Using algebraic expressions, we figured out that Thomas has 74 quarters and 82 dimes in his change jar, based on the total value of $26.70 and the fact that he has 8 more dimes than quarters.

To solve the problem involving the collection of dimes and quarters in Thomas's change jar, we need to use algebra. Let's define the variables first: let q be the number of quarters and q + 8 be the number of dimes since Thomas has 8 more dimes than quarters.

Since each quarter is worth $0.25 and each dime is worth $0.10, we can set up the following equation to represent the total amount of money ($26.70):

0.25q + 0.10(q + 8) = 26.70

Now, we simply solve for q:

Therefore, Thomas has 74 quarters. To find the number of dimes:

q + 8 = 74 + 8 = 82

Thus, Thomas has 82 dimes.

Thomas's change jar has a total of 74 quarters and 82 dimes.

solve for x

minus y² from both sides

[tex]x^2=100-y^2[/tex]

sqare root both sides

[tex]x=\sqrt{100-y^2}[/tex]

the answer is the 4th option

An equation represents the value of x is x=√100-y².Therefore, option D is the correct answer.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

From the given triangle ABC, AB=x units, BC=y units and AC=10 units

By using Pythagoras's theorem, we get

10²=x²+y²

x²=100-y²

x=√100-y²

Therefore, option D is the correct answer.

The maximum revenue for the computer company is achieved at the price of $11 per box which is calculated based on the decrease in quantity sold with every $1 increase in price.

To find the price per box that will provide the maximum revenue for the computer company, we need to analyze how changes in price affect the number of boxes sold and the revenue generated. The company sells 130 boxes of printer paper each week at $9 per box. For each $1 increase in price, it will sell 10 fewer boxes.

Let's define the revenue function as R(p) where p is the price per box. The initial revenue is 130 boxes × $9. For each $1 increase, the revenue function becomes (130 - 10(p - 9)) × p. We need to find the value of p that maximizes this revenue function.

Let's calculate:

We can see that the revenue is maximum at $11 per box. So, the price per box that will provide the maximum revenue for the computer company is $11.
